The two twelve year old half-vampire sisters Silvania and Dakaria Tepes move from Transylvania to a small German town, together with their father Mihai (a vampire) and their (human) mother Elvira. This is a culture shock for the two very dissimilar sisters. While Darkaria does not fit in the human world, Silvania is enjoying her humanness. In the school they find no right connection, although between Jacob and Silvania, a little romance seems to develop. The hard of hearing Helene, who hides her disability however is only girlfriend.
